What are GRP Cabinets?
GRP cabinets are protective enclosures manufactured from Glass Reinforced Plastic, a strong composite material widely used to protect electrical, utility and control equipment.
GRP is particularly well suited to outdoor and industrial environments because it is resistant to corrosion, moisture and weathering. Unlike conventional steel cabinets, GRP does not rust, making it a practical low-maintenance option for exposed installations.
These cabinets can be used to house electrical panels, controls, metering equipment, telecommunications hardware and other sensitive equipment that needs protection from the surrounding environment.
Adept GRP cabinets are available in a wide selection of standard sizes, allowing customers to select an enclosure appropriate to the equipment and installation rather than relying on a one-size-fits-all solution.
Should you have any questions please contact our customer services team or email sales@adeptgrp.co.uk.
Why Choose GRP Cabinets?
Corrosion and Weather Resistance
Our GRP cabinets provide durable protection for valuable electrical and utility equipment. Resistant to UV exposure, corrosion and harsh weather conditions, they are well suited to demanding outdoor environments. GRP also offers excellent insulating properties, helping protect internal equipment while reducing the need for ongoing corrosion-related maintenance.
Suitable for Electrical and Utility Equipment
GRP cabinets are widely used to protect electrical panels, controls, distribution equipment, metering systems and other sensitive components. Their durable construction, insulating properties and resistance to environmental conditions make them particularly suitable for electrical, utility and infrastructure applications where equipment requires secure protection both indoors and outdoors.
Low-Maintenance Outdoor Protection
One of the key advantages of GRP is its resistance to corrosion. Unlike conventional steel enclosures, GRP does not rust, helping to reduce the need for ongoing corrosion treatment or repainting.
Routine inspection of seals, hinges, locks and fixings is still recommended, but GRP provides a durable, low-maintenance enclosure solution for equipment installed in demanding environments.
GRP Cabinet IP Ratings
The correct IP ratings for a GRP cabinet depends on the equipment being protected and the environment in which the enclosure will be installed.
Our standard GRP cabinets provide protection suitable for a wide range of electrical, utility and outdoor applications. Where increased protection against dust and water ingress is required, an IP65 upgrade is available as an optional product extra for £225 + VAT.
IP65 may be particularly useful for installations exposed to more demanding weather conditions, dust or water. If you are unsure which specification is suitable for your project, our team can help you choose the appropriate cabinet and protection level.
GRP Cabinet Sizes
Adept offers 16 standard GRP cabinet sizes, providing options for everything from compact electrical installations through to larger outdoor equipment and control systems.
Choosing the correct cabinet involves more than simply matching the dimensions of the equipment. You should also allow sufficient space for cabling, internal components, ventilation, access and any future expansion.
When selecting your GRP cabinet, consider:
- Equipment width, depth and height
- Internal working clearance
- Cable entry requirements
- Ventilation requirements
- Door access
- Internal shelving or fittings
- Locking and security requirements
- Space for future equipment
If one of our standard sizes does not meet your requirements, we can also provide bespoke GRP enclosures for projects requiring non-standard dimensions or specifications.
Where Are GRP Cabinets Used?
GRP cabinets are suitable for a wide range of electrical, utility, infrastructure and industrial applications. Their combination of durability, corrosion resistance and weather resistance makes them particularly useful where equipment needs reliable protection from the surrounding environment.
Electrical Installations
GRP cabinets can be used to house electrical panels, distribution equipment, controls, switches, cabling and associated components.
Their insulating properties and resistance to corrosion make them a practical enclosure option for both indoor and outdoor electrical installations.
Utility and Infrastructure Applications
GRP cabinets are commonly used within utility and infrastructure projects where equipment needs to remain protected from moisture, weather and environmental exposure.
Applications can include electrical distribution, metering, telecommunications and other essential infrastructure equipment. Their durable construction, insulating properties and resistance to environmental conditions make them particularly suitable for electrical, utility and infrastructure applications where equipment requires secure protection both indoors and outdoors.
Roadside Cabinets
Roadside installations can be exposed to rain, moisture, UV and changing weather conditions throughout the year.
GRP provides a corrosion-resistant enclosure material capable of protecting sensitive equipment in exposed roadside environments while keeping maintenance requirements relatively low.
Industrial Environments
GRP cabinets are well suited to industrial and commercial sites where electrical and control equipment requires durable protection from weather, corrosion and environmental exposure.
For infrastructure projects requiring a different enclosure format, our GRP kiosks are designed for outdoor electrical, telecoms, utilities, lighting and EV charging applications. Standard kiosk sizes are available for common equipment-housing requirements, with bespoke manufacturing available where a standard size does not suit the installation.
GRP Cabinet Options and Customisation
Every installation is different, which is why our GRP cabinets can be supplied with a range of additional options to suit different project requirements.
Available options can include:
- Load-bearing or non-load-bearing floors
- Forced or natural ventilation
- Cable entry points
- Viewing windows
- Enhanced locking mechanisms
- Lightweight shelving
- Adjustable hinges
- Optional IP65 upgrade
These options allow the enclosure to be configured around the equipment being housed, the installation environment and the level of access or protection required.
If you require a non-standard cabinet configuration, our team can help identify the most appropriate solution for your project.
Ventilation and Cable Entry
Ventilation and cable management should be considered when specifying any enclosure that will house electrical or control equipment.
Equipment that generates heat may require natural or forced ventilation to help manage the temperature inside the cabinet. The appropriate ventilation solution will depend on the equipment installed and the conditions in which the cabinet will operate.
Cable routing should also be planned before installation. Cable entry points can be incorporated into the cabinet specification to help provide suitable access for incoming and outgoing cables.
Other options such as internal shelving, viewing windows and enhanced locking can also be considered depending on the application.
How to Choose the Right GRP Cabinet
Choosing the right GRP cabinet depends on the size of the equipment, the installation environment and any requirements for ventilation, cable entry, access or future expansion.

GRP Cabinet FAQs
Find answers to common questions about GRP cabinets, including sizes, outdoor use, IP ratings, customisation and delivery.
What are GRP cabinets?
GRP cabinets are protective enclosures manufactured from Glass Reinforced Plastic. They are commonly used to protect electrical, utility, control and telecommunications equipment from weather, moisture, corrosion and other environmental conditions.
What does GRP stand for?
GRP stands for Glass Reinforced Plastic. It is a strong composite material made using resin reinforced with glass fibres and is widely used for outdoor cabinets and enclosures because of its durability and corrosion resistance.
Are GRP cabinets suitable for outdoor use?
Yes. GRP cabinets are particularly well suited to outdoor environments because they are resistant to corrosion, moisture, UV exposure and changing weather conditions.
Do GRP cabinets rust?
No. GRP does not rust like conventional steel, which makes it a practical choice for roadside, utility, electrical and industrial installations where corrosion resistance is important.
